What do you think?

He instinctually took a step back, but he almost felt a ****, pushing him forwards.

Don't worry! You're fine.

With the last of his resolve gone, James could wait no longer. He stepped up behind Sophie, and thrust himself deep inside of her, thoroughly enjoying her cries. As he pushed in, he watched as she reached forwards and began opening the window. A heartbeat of horror filled him, before he pushed it aside.

Fuck it. He thought to himself. I'm in now!

He grabbed her hips and began plunging himself inside her with reckless abandon. Every cry. Every whimper that came from her, he was filled with a deep, resounding pleasure.

It only took about 30 seconds before he spotted his neighbour's walking by. Sally and Steve. People he'd known since he and Sophie were kids. James made eye contact and stopped what he was doing, watching them intently, bracing himself for the cries of shock and horror.

However, they just smiled.

"Hey guys! Just having an evening workout?" called Sally.

James just stared dumbfounded. Thankfully, Sophie responded.

"Yep! What about you?" she replied, pushing herself against her brother, glaring at him in frustration.

"We just thought we'd have a stroll over to that new sex club in town!" shouted Steve.

"Oh yeah? What's it called? Horizon!" she said, looking back at James. "Carry on!"

At that moment, James didn't think he could move. But one look at his sister, and he couldn't resist. He began pounding as hard as he could once more, keeping close attention to the conversation. He didn't want to miss a second. Her cries once again filled the room and beyond.

"That's the one yes!" Steve shouted back. "Anyway, we'll let you both carry on! Sorry to disturb you!"

And the two trotted off.

Sophie pulled James out, and flipped over onto her back, reinserting him as she did.

"Well? Does that prove that whatever bullshit you were on about is a load of crap?"

James ignored her. His desire getting the better of him. He once again, leant forward and kissed the life out of her, driving his member inside of her as hard and fast as he could. After a minute or so, he felt his orgasm beginning to build.

"I'm gonna-" he started, and he tried to pull out.

However, her legs locked around his back.

"Don't you fucking dare!" she shouted. "I'm almost-" she panted, before letting out a long, loud cry.

That was too much for him. The clenching. The cries. The...the...everything. James released himself inside of her with the intensity of what felt like years of orgasms. He had never experienced anything as powerful as this. Part of him worried the **** of it may send him flying backwards. But alas, that is impossible, and James is not quite that much of a stud.

For about 5 minutes, all that could be heard in the room was the sound of the pair of them panting heavily. Eventually, Sophie got up, and flung herself onto the sofa.

"I dunno about you," she gasped. "But I have never experienced anything like that."

James flung himself next to her, nodding in agreement. After a moment, she turned and smiled at him.

"Who needs a girlfriend, eh?" she said, before pushing her spent body on to his, and giving him a long, deep kiss.

The two collapsed onto the couch together, arms and legs entwined, before drifting off into a peaceful sleep.
